Semi-physical simulation platform and method suitable for industrial control safety test

Abstract

The invention discloses a semi-physical simulation platform and method suitable for an industrial control safety test. The system comprises a monitoring system which is used for realizing real-time and synchronous acquisition and storage of simulation data of a simulation monitoring platform and has functions of data storage and recording, OPC communication and the like; and a simulation model which is positioned in the monitoring terminal computer and is used for monitoring a data source of the system. In the model, the MATLAB is used for simulating the control operation process of the industrial system and acquiring related data; meanwhile and serving as an OPC server to provide an objectified data transmission function for a client, a shared variable engine SVE provided by LabVIEW serves as an OPC client to interact with dynamic simulation, various physical quantities are monitored, and an alarm is given in time for the phenomena of threshold exceeding or normal change frequency andthe like, so that the purpose of discovering exceptions is achieved. And meanwhile, a serial port and a protocol port of the DAQ data end are connected with the PLC, and the simulation data are sentto a PLC entity. The platform can effectively reflect the condition of attacked ICS system data through the change of the physical quantity.

Description

technical field [0001] The invention belongs to the technical field of industrial control safety simulation analysis, and in particular relates to an interactive dynamic simulation monitoring platform and method for an industrial control system. Background technique [0002] Industrial control system ICS is generally composed of SCADA, DCS, PLC, RTU and other parts, and is widely used in important fields such as electric power, petrochemical industry, rail transit, etc. that involve the national economy and people's livelihood. Information security research methods mainly include field testing, theoretical analysis and simulation testing. Because the industrial control system is very basic, complex and specialized, and ICS is a continuous operating system, the intrusive methods such as vulnerability scanning and penetration testing used in traditional IT system risk assessment will have an impact on system operation. A semi-physical simulation platform suitable for industri...

AI Technical Summary

Problems solved by technology

Since the industrial control system is highly basic, complex and specific, and ICS is a continuous operation system, intrusive methods such as vulnerability scanning and penetration testing used in traditional IT system risk assessment will have an impact on system operation, so promote a A hardware-in-the-loop simulation platform suitable for industrial control security testing is necessary

At present, the industry mostly uses network simulation for testing, but to analyze the impact of various industrial control attacks on physical systems, the coverage and professionalism of network simulation are not enough

In addition, many network attack effects can only be discovered through professional analysis, and cannot be verified and displayed on the real system, especially the part related to the controller hardware, which cannot be proved unless there is a failure or an accident, which is not conducive to the early detection of problems

Compared with real network equipment components, traditional simulation lacks interactivity, cannot discover other types of attacks with strong concealment and lag, and cannot truly reflect the situation of malicious attacks on cyber-physical systems in ICS
